You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

[Ivan]’s LCD was ... The display featured no onboard controller, and the original driver wasn’t easily repurposed. Instead, [Ivan] decided to drive it directly from an Arduino Uno.

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

You can see our main controller, the “Arduino UNO R3”, is responsible for handling signals from IR sensors and doing some computation to calculate the speed of the object. Here in the below picture, ...

I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I got both ICs working in separate sketches that I’ve blogged about previously, but I wanted one combined program.

Here in my case, I have included “LiquidCrystal_I2C.h” library for using the I2C interface of an LCD display and “Wire.h” for using I2C functionality on Arduino. Then, sort the Analog values received ...

Both the reference and the measured values are displayed on the Liquid Crystal Display (LCD). The Arduino microcontroller, being the processing unit of the system, gets the sensor's measured value and ...
